CRC3A4E121GT

CRC3A4E121GT Description

The CRC3A4E121GT from KYOCERA AVX is a high-precision 1206 (3216 Metric) surface-mount resistor network designed for compact, high-density PCB applications. This 4-resistor isolated array offers a 120Ω resistance per element with a tight ±2% tolerance and a ±250ppm/°C temperature coefficient, ensuring stable performance across varying environmental conditions. Encased in a convex, long-side terminal package, it features a low-profile 0.024" (0.60mm) height, making it suitable for space-constrained designs. The product is rated for 62.5mW power dissipation per element and complies with REACH and EAR99 regulations, though it is marked as Obsolete in KYOCERA AVX's lineup. Packaged in Tape & Reel (TR) for automated assembly, it is ideal for high-volume manufacturing.

CRC3A4E121GT Features

• Compact 1206 Footprint: Measures 0.126" x 0.063" (3.20mm x 1.60mm), optimizing board space.
• High Precision: ±2% tolerance and ±250ppm/°C TCR ensure reliable signal integrity.
• Robust Construction: Convex, long-side terminals enhance mechanical stability and solder joint reliability.
• Low-Profile Design: 0.60mm seated height suits thin-profile applications.
• Automation-Ready: Tape & Reel packaging streamlines pick-and-place processes.
• Compliance: Meets REACH and EAR99 standards, though obsolete for new designs.

CRC3A4E121GT Applications

This resistor network excels in:

• Precision Analog Circuits: Voltage dividers, sensor interfaces, and feedback networks where tolerance stability is critical.
• Consumer Electronics: Space-efficient designs in smartphones, wearables, and IoT devices.
• Industrial Controls: Signal conditioning in PLCs, motor drives, and instrumentation.
• Automotive Electronics: Non-safety-critical systems requiring stable resistance under thermal stress.
• Legacy Repairs: Maintenance of older PCB designs originally specifying this obsolete part.

Conclusion of CRC3A4E121GT

The CRC3A4E121GT balances precision, compactness, and reliability, making it a strong choice for legacy or niche applications demanding tight-tolerance resistor networks. While obsolete, its 1206 form factor, low thermal drift, and automation-friendly packaging ensure continued utility in repair or low-volume production. Engineers should evaluate alternative modern equivalents for new designs but may leverage this part for compatibility with existing systems.
