CRA04P0839K10JTD

CRA04P0839K10JTD Description

The CRA04P0839K10JTD from Vishay Dale is a high-performance, surface-mount resistor network designed for precision applications in compact electronic assemblies. Part of the CRA04 series, this device integrates four isolated 9.1kΩ resistors in an ultra-thin 0804 concave long-side terminal package, measuring just 2.00mm x 1.00mm (0.079" x 0.039") with a seated height of 0.55mm (0.022"). It offers a ±5% tolerance and a ±200ppm/°C temperature coefficient, ensuring stable performance across varying environmental conditions. With a 62.5mW power rating per element, it balances power dissipation and space efficiency, making it ideal for densely populated PCBs.

CRA04P0839K10JTD Features

• Compact Design: 0804 concave package optimizes board space while facilitating automated assembly.
• High Reliability: ROHS3 compliant and MSL 1 (Unlimited) moisture sensitivity ensures compatibility with lead-free processes and long-term durability.
• Precision Performance: ±5% tolerance and ±200ppm/°C TCR provide consistent resistance values under thermal stress.
• Isolated Circuit Configuration: Each resistor is electrically isolated, reducing crosstalk in multi-channel applications.
• Tape & Reel Packaging: Supports high-volume pick-and-place manufacturing.

CRA04P0839K10JTD Applications

This resistor array excels in applications demanding miniaturization and reliability, such as:

• Consumer Electronics: Voltage division and signal conditioning in smartphones, wearables, and IoT devices.
• Industrial Controls: Precision current limiting and pull-up/pull-down networks in PLCs and sensors.
• Automotive Systems: Engine control units (ECUs) and infotainment systems where space and stability are critical.
• Medical Devices: Portable diagnostic equipment requiring tight tolerance components.

Conclusion of CRA04P0839K10JTD

The CRA04P0839K10JTD combines Vishay Dale's expertise in passive components with a form factor tailored for modern electronics. Its compact size, isolated resistors, and robust performance make it a superior choice over bulkier discrete alternatives. While marked obsolete, it remains a viable solution for legacy designs or applications where its specific attributes are unmatched.
