Carbon Resistor 22Ω 0.25W Through Hole
The RS Pro 22 Ω, 0.25 W through‑hole carbon film resistor is built around a ceramic rod substrate, over which a precision carbon‑film resistive element is deposited. Encased in a tough epoxy resin, its slim axial‑lead form (6.3 mm long, 2.3 mm diameter) enables straightforward insertion and soldering on standard PCBs, while the epoxy finish provides excellent resistance to solvents, abrasion, and chipping.
Rated for 0.25 W dissipation at 70 °C with ±5% tolerance, it delivers reliable, low‑noise performance across a broad ambient range (–55 °C to +155 °C). Its temperature coefficient (–500 to +350 ppm/°C) ensures predictable drift in varying thermal conditions, making it suitable for cost‑sensitive general‑purpose circuits.
Manufactured with solder‑plated copper leads and a rugged welded‑cap construction, this resistor withstands mechanical stress and moisture ingress. Tested to IEC 115/115‑2 standards, it balances affordability and stability for consumer, automotive, telecom, and medical electronics without premium branding costs.
Features:
- Available in resistances from 1 Ω to 9.1 MΩ.
- Compact 2.3 mm × 6.3 mm body.
- Long‑term resistance stability.
- Epoxy coating for moisture and solvent resistance.
- Standard solder‑plated copper axial leads.
