Various types of standard circuits in different sizes and power are available. (Seated height 5.08mm, 6.5mm, 10.7mm Max.)
・
For automatic insertion machines, stick magazines (the tip of lead terminal is cut to a V shape) and taping packages (TBA: All leads taping, TPA, TUA:3 leads
taping) are applicable.
・
Products with lead free termination meet EU-RoHS requirements. EU-RoHS regulation is not intended for Pb-glass contained in electrode, resistor element and
glass.

The terminal surface material lead free is standard.
Contact us when you have control request for environmental hazardous material other than the substance specified by
EU-RoHS.
For further information on taping, please refer to APPENDIX C on the back pages.
Specifications given herein may be changed at any time without prior notice. Please confirm technical specifications before you order and/or use.
Contact our sales representatives before you use our products for applications including automotives, medical equipment and aerospace equipment.
Malfunction or failure of the products in such applications may cause loss of human life or serious damage.
For resistors operated at an ambient temperature of 70℃ or higher, the power shall be derated in accordance with the above derating curve.
■Precautions for Use
・The
conditions of flow soldering for lead-free terminal resistors are set up at 260℃ max. within 10 sec.
・A
few cross talks will happen in network resistors. Design the circuit taking the effect by the cross talks into consideration as very low voltage will occur to the
resistor elements that don’t pass current by the voltage drop in common electrode if current flows to the common electrodes.
Specifications given herein may be changed at any time without prior notice. Please confirm technical specifications before you order and/or use.
Contact our sales representatives before you use our products for applications including automotives, medical equipment and aerospace equipment.
Malfunction or failure of the products in such applications may cause loss of human life or serious damage.
