RKC8BD471J

RKC8BD471J Description

The RKC8BD471J from KOA Speer Electronics, Inc. is a thick film resistor network designed for high-density circuit applications. This 8-resistor network features a 470Ω resistance value per resistor with a 5% tolerance, ensuring reliable performance in precision circuits. Encased in a 9-pin SIP (Single In-line Package), it offers a compact footprint (23.4mm length, 6.5mm height) with through-hole mounting for secure PCB integration. Rated for 1W total power dissipation (0.125W per resistor) and a wide operating temperature range of -55°C to +155°C, it excels in demanding environments. The ±200ppm/°C temperature coefficient and 200V maximum voltage rating further enhance its stability in variable conditions.

RKC8BD471J Features

• High-Density Integration: 8 resistors in a single SIP package (9 pins), saving PCB space.
• Robust Performance: Thick film technology ensures durability and consistent resistance values.
• Wide Temperature Range: Operates from -55°C to +155°C, with derated power up to 155°C.
