Carbon Resistor 100kΩ 0.125W Through Hole

The Carbon Resistor 100 kΩ 0.125 W Through‑Hole is a general‑purpose axial carbon‑film resistor engineered for cost‑effective insertion into printed circuit boards. With a compact ceramic body measuring 1.85 mm in diameter and 3.5 mm in length, it delivers a precision resistance of 100 kΩ, suitable for signal conditioning, biasing, and pull‑up/pull‑down networks. Its through‑hole leads (0.45 mm diameter, 28 mm length) ensure reliable mechanical support and ease of assembly in both automated and manual soldering processes.

Built around a carbon‑film element deposited on a ceramic substrate, this resistor is epoxy‑coated for protection against moisture, solvents, and minor mechanical abrasion. The film formulation yields a temperature coefficient of 0 to –700 ppm/°C over the 100 kΩ to 1 MΩ range, minimizing drift in environments with fluctuating temperatures. The robust axial leads are solder‑plated to promote strong solder joints and long‑term stability under thermal cycling.

Rated for continuous dissipation of 0.125 W at 70 °C ambient, with a maximum working voltage of 200 V and overload capability up to 400 V, this resistor endures standard assembly stresses. It meets IEC standards for short‑time overload, insulation resistance (≥1 000 MΩ), dielectric withstanding, and solderability, ensuring consistent performance in consumer electronics, instrumentation, and low‑power applications.

Features:

• Automatically insertable, suitable for high‑speed assembly.
• Epoxy‑coated, non‑flammable option available.
• Cost‑effective carbon‑film technology.
• Standard tolerance: ±5% (implied by part numbering).
