PCF Ceramic Fixed Power Resistors

KOA Speer PCF Ceramic Fixed Power Resistors feature a power rating range of 0.5W to 2W and tolerance of ±10%. These devices feature color-coded bands and lead-free terminations and are coated with UL94v-0 flame-proof material. KOA Speer PCF resistors can replace carbon composition resistors in most applications and are suitable for automatic machine insertion.
