Metal Film Chip Resistors

■ Recommended Land Pattern

In case of ﬂow soldering, the land width must be smaller than the Chip Resistor width to properly control the solder amount

properly. Generally, the land width should be 0.7 to 0.8 times (W) of the width of chip resistor. In case of reﬂow soldering,

solder amount can be adjusted, therefore the land width should be set to 1.0 to 1.3 times chip resistor width (W).

■ Recommended Soldering Conditions

Recommendations and precautions are described below.

Recommended soldering conditions for reﬂow

●

· Reﬂow soldering shall be performed a maximum of

two times.

· Please contact us for additional information when

used in conditions other than those speciﬁed.

· Please measure the temperature of the terminals

and study every kind of solder and printed circuit

board for solderability before actual use.

Safety Precautions

The following are precautions for individual products. Please also refer to the precautions common to Fixed Resistors

shown on page ER2 of this catalog.

1. Keep the rated power and ambient temperature within the speciﬁed derating curve.

* When positioning and mounting Metal Film Chip Resistors (hereafter called the resistors), make allowance for the

effect of heat generated through close contact between the resistors and neighboring components and for the

temperature rise of adjacent heat-generating components.

2. If a transient load (heavy load in a short time) like a pulse is expected to be applied, check and evaluate the operations

of the resistors when installed in your products before use.

When applying pulses to the resistors, keep the pulse peak within the rated voltage.

3. Do not use halogen-based or other high-activity ﬂux. Otherwise, the residue may impair the resistors' performance

and/or reliability.

4. When soldering with a soldering iron, never touch the resistors' bodies with the tip of the soldering iron. When using a

soldering iron with a high temperature tip, ﬁnish soldering as quickly as possible (within three seconds at 350 °C max.).

5. As the amount of applied solder becomes larger, the mechanical stress applied to the resistors increases, causing

problems such as cracks and faulty characteristics. Avoid applying an excessive amount of solder.

6. When the resistors' protective coatings are chipped, ﬂawed, or removed, the characteristics of the resistors may be

impaired. Take special care not to apply mechanical shock during automatic mounting or cause damage during

handling of the boards with the resistors mounted.

7. Do not apply shock to the resistors or pinch them with a hard tool (e.g. pliers and tweezers). Otherwise, the resistors'

protective coatings and bodies may be chipped, affecting their performance.

8. Avoid excessive bending of printed circuit boards in order to protect the resistors from abnormal stress.

9. Do not immerse the resistors in solvent for a long time. Before using solvent, carefully check the effects of immersion.

Design and speciﬁcations are each subject to change without notice. Ask factory for the current technical speciﬁcations before purchase and/or use.
