Carbon Resistor 43 Ohm 1/4Watt

Carbon Resistor 43 Ohm 1/4Watt Through Hole

The  Carbon Resistor 43 Ohm 1/4Watt through-hole carbon-film resistor is an axial, epoxy-coated component designed for PCB mounting and general-purpose electronic use. It has a compact ceramic body (approximately 2.33 mm diameter × 6.3 mm length) with axial leads for easy insertion and soldering. Marked with color bands for value recognition, the part presents a small footprint that fits well in tight board layouts and breadboard prototyping.

Manufactured using carbon film on a ceramic core, the resistor provides stable resistance at low cost and exhibits long-term stability under typical environmental conditions. Rated for 1/4 watts dissipation (at 70 °C in free air), it handles everyday signal and biasing tasks in low-power circuits. The leads are solder-plated copper for reliable solder joints, and the epoxy coating is resistant to solvents, abrasion, and chipping to protect markings and the resistive film.

Performance is characterized by moderate temperature coefficient and broad operating temperature limits (from −50 °C to +155 °C), making it suitable for hobbyist, repair, and many commercial applications where tight precision is not required. The rugged welded cap-and-lead construction improves mechanical strength; users should avoid prolonged exposure to excessive heat during soldering to preserve stability and markings.

 

Features:

• Available in resistances from 1 ohm to 47 MOhm.
• Compact axial body (≈2.33 mm × 6.3 mm).
• Long-term stability.
• Solder-plated copper leads.
• Epoxy resin coating highly resistant to solvents, abrasion and chipping.
• Rugged welded cap-and-lead construction for improved mechanical strength.
• Low noise and high reliability.
• Rated at 70 °C in free air.
