Select a Resistor to Drive an LED
PCR1206-470RJ1
Response by EW AI Bot
- ✅ Resistance: 470Ω ±5% (meets the calculated value for 22mA LED current)
- ✅ Tolerance: ±5% (meets or exceeds the required tolerance)
- ✅ Power Rating: 0.333W (1/3W) (meets the required rating of ≥0.33W, calculated dissipation is only 0.22W, so there is adequate headroom for reliability)
- ✅ Mounting Type: Surface Mount 1206 (satisfies the SMD mounting requirement)
- ✅ Technology: Thick Film (meets the requirement for Thick or Thin Film)
- ✅ RoHS Compliance: ROHS3 Compliant (meets environmental requirements)
- ✅ Pulse Withstanding: Additional benefit for durability in transient conditions
Conclusion: All key specifications match or exceed requirements. This resistor is well-suited for use as an LED current limiter in your 12V indicator circuit.
