RKL8BD103G

RKL8BD103G Description

The RKL8BD103G from KOA Speer Electronics, Inc. is a conformal-coated, thick-film resistor network designed for precision applications requiring stable performance in demanding environments. This 8-resistor network features a 10K Ohm resistance per element with a tight 2% tolerance and a low ±200ppm/°C temperature coefficient, ensuring reliable operation across a wide -70°C to +125°C temperature range. Housed in a 9-pin SIP (Single In-line Package), it offers a 1W total power rating (0.125W per resistor) and supports 100V maximum voltage. The conformal coating enhances durability against moisture and contaminants, making it suitable for industrial and harsh-condition applications.

RKL8BD103G Features

• High Reliability: Thick-film technology with conformal coating for improved environmental resistance.
• Precision Performance: 2% tolerance and ±200ppm/°C TCR ensure consistent signal integrity.
• Robust Construction: Through-hole pin termination with 2.54mm pitch for secure PCB mounting.
• Wide Operating Range: Derated power capability up to 125°C, ideal for high-temperature environments.
• Space-Efficient: Compact 22.86mm × 2.5mm × 5.08mm SIP package saves board space.
• Compliance: EU RoHS compliant (with exemption) and EAR99 ECCN for global usability.

RKL8BD103G Applications

This resistor network excels in:

• Analog/Digital Signal Conditioning: Voltage division, pull-up/pull-down networks in industrial control systems.
• Automotive Electronics: Non-automotive but suitable for harsh-environment sensors (e.g., HVAC, lighting).
• Power Supplies: Current-limiting and feedback circuits in DC-DC converters.
• Test & Measurement Equipment: Precision resistor arrays for calibration and instrumentation.
• Consumer Electronics: Durable solutions for appliances and IoT devices exposed to humidity.

Conclusion of RKL8BD103G

The RKL8BD103G stands out for its conformal-coated durability, precision thick-film resistors, and SIP packaging, offering a balance of performance and ruggedness. While not PPAP or automotive-qualified, its wide temperature range and high-voltage tolerance make it a versatile choice for industrial, power, and measurement applications. Its bulk packaging and through-hole design further simplify integration for high-reliability designs.
