CAT25-101JALF

CAT25-101JALF Description

The CAT25-101JALF by Bourns Inc. is an 8-resistor bussed network array designed for high-density surface-mount applications. Housed in a compact 1608 package (4.00mm x 2.10mm) with concave, long-side terminals, it offers a 100Ω resistance per element with a ±5% tolerance and a ±200ppm/°C temperature coefficient. The device operates at 62.5mW power per element and is rated for MSL 1 (Unlimited) moisture sensitivity, ensuring reliability in humid environments. Compliant with ROHS3 and REACH standards, this obsolete-but-still-relevant component is supplied in Tape & Reel (TR) packaging for automated assembly efficiency.

CAT25-101JALF Features

• High-Density Integration: 8 resistors in a 10-pin, ultra-low-profile (0.65mm height) package, ideal for space-constrained PCBs.
• Stable Performance: Low ±200ppm/°C thermal drift ensures consistent resistance across temperature variations.
• Automation-Friendly: Concave terminal design enhances solder joint reliability during reflow processes.
• Compliance: Meets ROHS3 and EAR99 regulations, suitable for global markets.
• Bussed Circuit: Simplifies design by connecting resistors in a common-node configuration, reducing layout complexity.

CAT25-101JALF Applications

• Consumer Electronics: Voltage division and pull-up/down networks in smartphones, wearables, and IoT devices.
• Industrial Controls: Signal conditioning and termination in PLCs, sensors, and motor drives.
• Automotive Systems: Auxiliary circuits in infotainment or dashboard modules (non-safety-critical).
• Telecom Hardware: Impedance matching in RF modules and baseband processing units.

Conclusion of CAT25-101JALF

The CAT25-101JALF balances compactness, stability, and ease of integration, making it a pragmatic choice for legacy designs or replacements in cost-sensitive, high-volume applications. While obsolete, its ROHS3 compliance and robust performance retain relevance in industries prioritizing reliability over cutting-edge availability. Engineers should evaluate alternative Bourns series for new designs but may leverage this model for repairs or BOM optimization.
