CRB2A4E390JT

CRB2A4E390JT Description

The CRB2A4E390JT from KYOCERA AVX is a compact, surface-mount resistor network designed for high-density PCB applications. Part of the CRB series, this 4-resistor array features isolated 39Ω resistors with a ±5% tolerance and a ±250ppm/°C temperature coefficient. Encased in an 0804 concave package (2.00mm x 1.00mm x 0.50mm), it offers a low-profile footprint ideal for space-constrained designs. With a power rating of 62.5mW per element and long-side terminals for robust solder joints, this obsolete but reliable component remains suitable for legacy or low-risk applications. Its REACH Unaffected status and EAR99 ECCN ensure compliance with environmental and export regulations.

CRB2A4E390JT Features

• Compact Design: Ultra-thin 0.50mm height and 0804 footprint optimize board space.
• Stable Performance: ±250ppm/°C thermal stability ensures consistent operation across temperature variations.
• High Reliability: Concave package with long-side terminals enhances mechanical and thermal stress resistance.
• Compliance: Meets HTSUS 8533.21.0020 and MSL 1 (Unlimited) standards for moisture sensitivity.
• Ease of Assembly: Supplied in Tape & Reel (TR) packaging for automated SMT processes.

CRB2A4E390JT Applications

This resistor array excels in precision analog and digital circuits, including:

• Signal Conditioning: Voltage dividers or pull-up/down networks in sensor interfaces.
• Consumer Electronics: Space-saving solutions for smartphones, wearables, and IoT devices.
• Industrial Controls: Isolated resistor networks for PLCs or motor drivers.
• Legacy Systems: Maintenance or repair of older equipment requiring discontinued 0804-form-factor parts.

Conclusion of CRB2A4E390JT

While marked obsolete, the CRB2A4E390JT remains a viable choice for designs prioritizing miniaturization and stable performance. Its Kyocera AVX pedigree ensures quality, and its niche package style (concave 0804) may be critical for specific layouts. Engineers should evaluate alternatives for new designs but can leverage this component for repairs or low-volume production where footprint compatibility is paramount.
