Ordering information


Y N : low inductance

XXX Model 700, 800, 1000, 1200

RRRR Resistance value (nominal at 20°C)


RCH 1000 15R 5%

RCH is the name of the product

15R means 15 Ω that is the nominal ohmic value at 20°C

5% is the tolerance on the ohmic value, in this case the value of the resistor is accepted when is within 14.25 Ω ÷ 15.75 Ω
