For complete environmental specifications,
please refer to pages 30-31.
The Trimmable chip resistor is suitable for the circuit demanding high
stability as a replacement of variable resistors for adjusting circuit.
Please note that customers need laser trimming equipment.
Trimming by laser increases the initial resistance. Amount of resistance
increase is dependent on the laser cut configuration as shown.
W1 must not exceed 1/2W to ensure power rating of the unit.
Specifications given herein may be changed at any time without prior notice. Please confirm technical specifications before you order and/or use.
