The energy absorbed by the resistor expressed in Joules can be calculated by

multiplying the peak power of the pulse in watts times the length of the pulse in

seconds.

The energy should not exceed the limits shown in the graph. The overload voltage

should not exceed 1.5 times the maximum operating voltage.

Legal Disclaimer Notice

This legal disclaimer applies to purchasers and users of Bourns^®products manufactured by or on behalf of Bourns, Inc. and its

afﬁliates (collectively, “Bourns”).

Unless otherwise expressly indicated in writing, Bourns^®products and data sheets relating thereto are subject to change

without notice. Users should check for and obtain the latest relevant information and verify that such information is current and

complete before placing orders for Bourns^®products.

The characteristics and parameters of a Bourns^®product set forth in its data sheet are based on laboratory conditions, and

statements regarding the suitability of products for certain types of applications are based on Bourns’ knowledge of typical

requirements in generic applications. The characteristics and parameters of a Bourns^®product in a user application may vary

from the data sheet characteristics and parameters due to (i) the combination of the Bourns^®product with other components

in the user’s application, or (ii) the environment of the user application itself. The characteristics and parameters of a Bourns^®

product also can and do vary in different applications and actual performance may vary over time. Users should always verify

the actual performance of the Bourns^®product in their speciﬁc devices and applications, and make their own independent

judgments regarding the amount of additional test margin to design into their device or application to compensate for

differences between laboratory and real world conditions.

Unless Bourns has explicitly designated an individual Bourns^®product as meeting the requirements of a particular industry

standard (e.g., ISO/TS 16949) or a particular qualiﬁcation (e.g., UL listed or recognized), Bourns is not responsible for any

failure of an individual Bourns^®product to meet the requirements of such industry standard or particular qualiﬁcation. Users of

Bourns^®products are responsible for ensuring compliance with safety-related requirements and standards applicable to their

devices or applications.

Bourns^®products are not recommended, authorized or intended for use in nuclear, lifesaving, life-critical or life-sustaining ap-

plications, nor in any other applications where failure or malfunction may result in personal injury, death, or severe property or

environmental damage. Unless expressly and speciﬁcally approved in writing by two authorized Bourns representatives on a

case-by-case basis, use of any Bourns^®products in such unauthorized applications might not be safe and thus is at the user’s

sole risk. Life-critical applications include devices identiﬁed by the U.S. Food and Drug Administration as Class III devices and

generally equivalent classiﬁcations outside of the United States.

Bourns expressly identiﬁes those Bourns^®standard products that are suitable for use in automotive applications on such

products’ data sheets in the section entitled “Applications.” Unless expressly and speciﬁcally approved in writing by two

authorized Bourns representatives on a case-by-case basis, use of any other Bourns^®standard products in an automotive

application might not be safe and thus is not recommended, authorized or intended and is at the user’s sole risk. If Bourns

expressly identiﬁes a sub-category of automotive application in the data sheet for its standard products (such as infotainment

or lighting), such identiﬁcation means that Bourns has reviewed its standard product and has determined that if such Bourns^®

standard product is considered for potential use in automotive applications, it should only be used in such sub-category of

automotive applications. Any reference to Bourns^®standard product in the data sheet as compliant with the AEC-Q standard

or “automotive grade” does not by itself mean that Bourns has approved such product for use in an automotive application.

Bourns^®standard products are not tested to comply with United States Federal Aviation Administration standards generally

or any other generally equivalent governmental organization standard applicable to products designed or manufactured for

use in aircraft or space applications. Bourns expressly identiﬁes Bourns^®standard products that are suitable for use in aircraft

or space applications on such products’ data sheets in the section entitled “Applications.” Unless expressly and speciﬁcally

approved in writing by two authorized Bourns representatives on a case-by-case basis, use of any other Bourns^®standard

product in an aircraft or space application might not be safe and thus is not recommended, authorized or intended and is at the

user’s sole risk.

The use and level of testing applicable to Bourns^®custom products shall be negotiated on a case-by-case basis by Bourns and

the user for which such Bourns^®custom products are specially designed. Absent a written agreement between Bourns and the

user regarding the use and level of such testing, the above provisions applicable to Bourns^®standard products shall also apply

to such Bourns^®custom products.

Users shall not sell, transfer, export or re-export any Bourns^®products or technology for use in activities which involve the

design, development, production, use or stockpiling of nuclear, chemical or biological weapons or missiles, nor shall they use

Bourns^®products or technology in any facility which engages in activities relating to such devices. The foregoing restrictions

apply to all uses and applications that violate national or international prohibitions, including embargos or international

regulations. Further, Bourns^®products and Bourns technology and technical data may not under any circumstance be

exported or re-exported to countries subject to international sanctions or embargoes. Bourns^®products may not, without prior

authorization from Bourns and/or the U.S. Government, be resold, transferred, or re-exported to any party not eligible

to receive U.S. commodities, software, and technical data.

To the maximum extent permitted by applicable law, Bourns disclaims (i) any and all liability for special, punitive, consequential,

incidental or indirect damages or lost revenues or lost proﬁts, and (ii) any and all implied warranties, including implied warranties

of ﬁtness for particular purpose, non-infringement and merchantability.
