for 10 000 h for use in Hybrid Circuits
FEATURES
FIGURE 1 - TRIMMING CHIP RESISTORS
• Temperature coefficient of resistance (TCR):
Absolute: ± 2.0 ppm/°C (- 55 °C to + 125 °C,
+ 25 °C ref.)
V5X5P
TCR tracking: to 0.5 ppm/°C (1)(2)
• Resistance tolerance:
Absolute to ± 0.01 % (user trimmable to ± 0.005 %)
Match: to 0.01 %
Trim Points
Gold Plated Pads
Gold Plated Pads
• Power rating: 50 mW to 150 mW at + 70 °C
• Load life stability: ± 0.01 % at + 70 °C, 10 000 h at rated
power
V15X5P
• Resistance range: 5 Ω to 80 kΩ (see table 2)
• Vishay Foil Resistors are not restricted to standard values;
specific “as required” values can be supplied at no extra
cost or delivery (e.g. 1K2345 vs. 1K)
• Hybrid chips are also available for high temperature
applications, please contact us for more details
V15X10P
• Short time overload: ≤ 0.02 %
• Electrostatic discharge (ESD) up to 25 000 V
• Non-inductive, non-capacitive design
• Rise time: 1 ns effectively no ringing
• Thermal stabilization time < 1 s (nominal value achieved
within 10 ppm of steady state value)
• Current noise: 0.010 µVRMS/V of applied voltage (< - 40 dB)
• Non-inductive: < 0.08 µH
Gold Plated Pads
• Pattern design minimizing hot spots
The typical pattern and trimming illustrations show that the
V5X5P resistor has 16 trimming points, the V15X5P has 20
and the V15X10P has 21. These trimming points are
arranged around the chip periphery and are clearly
indicated. Trimming to the desired resistance value and
tolerance is accomplished by cutting the trim points, thereby
producing specific incremental changes in the chip’s
resistance value relative to the original prevalue; up to
+ 20 % for the V5X5P, + 30 % for the V15X5P, and + 50 %
0.015 % ΔR maximum under full rated power for 2000 h at
+ 70 °C.
The Vishay precision trimming system allows for adjustment
to precise resistance values without concern over
mechanical override and control problems encountered in
laser or air abrade trimming of solid geometry resistance
patterns. This ability to trim resistor chips to tolerance levels
never before available to hybrid manufacturers, now gives a
project manager the ability to increase the value-added level
of their hybrid services. More of the profit thus available can
be retained within the facility. Now, instead of buying
precision resistors in separate packages or modules (which
require additional PC board real estate) and integrating them
into a system, the project manager can utilize Vishay
precision resistor chips or matched sets to manufacture the
entire hybrid circuit in-house. Eliminates the need to “pin-out”
for precision resistor requirements because the precision
resistors are inside - part of the hybrid microcircuit design.
for the V15X10P (not all trim points need be used; the ΔR
necessary to adjust the pre-value to the desired final value
dictates which trim points need to be used).
Monitoring of circuit output while “actively” trimming readily
permits adjustment of the chip to ± 0.005 %.
Actual trimming charts are supplied on request for all
images.
Vishay precision chip resistors offer an order of magnitude
of improvement over other chip resistors in hybrid
applications. With a maximum Temperature Coefficient of
Resistance (TCR) of ± 5 ppm/°C, selected TCR tracking to
0.5 ppm/°C and factory supplied resistance tolerances to
± 0.01 %, they provide the user with accuracy and stability
not available in other chip resistor products. If desired they
can be user trimmed to any value within ± 0.005 %, where
the value remains stable after trimming. Load life stability is
Vishay precision chip resistors are available either factory-
trimmed to exact resistance values (option T) or ready for
user trimming (option U); user trimming can be done either
before or after bonding - using standard epoxies - onto the
hybrid circuit substrate using standard laser, air abrade, or
manual adjustment techniques. However care should be
taken that no carbonization occurs when laser trimming.

TCR tracking is a measure of the similarity of resistance value change in two or more resistors which are undergoing the same temperature
changes. Tracking could be expressed as the difference in the temperature coefficients of the resistors, expressed in ppm/°C as (ΔR1/R1 -
ΔR2/R2) x 10-6/ΔT °C.
Selected TCR tracking is available for specially ordered lots of resistors. The selected TCR tracking can be 3, 2, 1 and as close as 0.5 ppm/°C
throughout the full temperature range. Should close TCR tracking be required for differing resistance values, contact the factory.
