CN2B4ATTE510J

CN2B4ATTE510J Description

The CN2B4ATTE510J by KOA Speer Electronics, Inc. is a thick film resistor network designed for precision surface-mount applications. This 4-resistor array features isolated (ISOL) circuit design with a resistance value of 51Ω per resistor, a tolerance of ±5%, and a temperature coefficient of ±200ppm/°C. Encased in a compact 8-pin convex SMD package (5.1mm x 1.6mm x 0.55mm), it offers a power rating of 0.125W (1/8W) per resistor and operates within a -55°C to +125°C temperature range. Compliant with EU RoHS (with exemption), this obsolete model is ideal for legacy designs requiring stable performance in constrained spaces.

CN2B4ATTE510J Features

• High-Density Integration: Four 51Ω resistors in an ultra-thin (0.55mm) SMD package optimize PCB space.
• Robust Performance: Thick film technology ensures reliability under derated power conditions (70°C to 125°C).
• Precision Tolerance: ±5% resistance tolerance and ±200ppm/°C TCR suit general-purpose circuits.
• Isolated Design: Independent resistors (ISOL) prevent cross-talk, ideal for multi-channel applications.
• Industry-Standard Pitch: 1.27mm terminal spacing simplifies automated assembly.

CN2B4ATTE510J Applications

This resistor network excels in:

• Signal Conditioning: Voltage division/pull-up in analog/digital interfaces (e.g., sensor modules).
• Legacy Electronics: Maintenance/repair of older SMD-based systems requiring discontinued components.
• Consumer Electronics: Dense PCBs in audio equipment, set-top boxes, or power management circuits.
• Industrial Controls: Isolated resistor networks for PLCs or motor driver feedback circuits.

Conclusion of CN2B4ATTE510J

The CN2B4ATTE510J balances compactness, isolation, and moderate precision, making it a pragmatic choice for space-constrained designs needing multi-resistor integration. While obsolete, its thick film durability and RoHS compliance (with exemption) ensure suitability for legacy or low-risk applications. Engineers should evaluate alternatives for high-reliability automotive or PPAP-qualified systems.
