RACF164DJT4K30

RACF164DJT4K30 Description

The RACF164DJT4K30 from Stackpole Electronics, Inc. is a compact, surface-mount resistor network designed for high-density PCB applications. Part of the RACF series, this 4-resistor array features isolated 4.3kΩ resistors with a ±5% tolerance and a ±200ppm/°C temperature coefficient. Encased in a 1206 (3216 Metric) concave, long-side terminal package, it measures 0.126" x 0.063" (3.20mm x 1.60mm) with a low-profile height of 0.030" (0.75mm). Rated at 62.5mW per element, it is RoHS3 compliant and REACH unaffected, making it suitable for environmentally conscious designs. Though obsolete, its robust construction and reliability make it a viable choice for legacy or low-volume production.

RACF164DJT4K30 Features

• High-Density Integration: Four isolated 4.3kΩ resistors in a single 1206 package save board space.
• Stable Performance: ±200ppm/°C temperature coefficient ensures consistent operation across varying thermal conditions.
• Concave Terminal Design: Long-side terminals enhance solder joint reliability and mechanical stability.
• Surface-Mount Ready: MSL 1 (Unlimited) rating allows extended storage without moisture sensitivity concerns.
• Compliance: Meets RoHS3 and REACH standards, suitable for global markets.
• Power Handling: 62.5mW per resistor balances compact size with adequate power dissipation.

RACF164DJT4K30 Applications

• Consumer Electronics: Ideal for signal conditioning in compact devices like wearables or IoT sensors.
