Overview
The TNPW08052K87BEEA is a precision thin-film resistor from Vishay's TNPW e3 series, designed for applications requiring high accuracy and stability. With a resistance value of 2.87kΩ and a tolerance of ±0.1%, this component is part of Vishay's high-performance passive components line. The 0805 package size (2.0mm × 1.25mm) makes it suitable for space-constrained applications while maintaining excellent electrical characteristics. These resistors are RoHS compliant and suitable for lead-free soldering processes.
Structure and Working Principle
The TNPW08052K87BEEA consists of a thin metal alloy film deposited on a high-grade ceramic substrate, laser-trimmed to achieve precise resistance values. The resistive element is protected by a robust coating that ensures long-term stability. Unlike thick-film resistors, thin-film technology provides better temperature stability and lower noise. The working principle relies on the controlled resistance of the thin metal film, which maintains consistent performance across various environmental conditions.
Key Features
This resistor offers several notable features including an extremely low temperature coefficient of ±25ppm/°C, ensuring minimal resistance variation with temperature changes. The ±0.1% tolerance makes it suitable for precision applications where exact resistance values are critical. The component has a power rating of 0.125W at 70°C and can withstand operating temperatures from -55°C to +155°C. Its excellent long-term stability (≤0.25% after 2000 hours at 70°C) makes it reliable for mission-critical applications.
Application Areas
The TNPW08052K87BEEA is commonly used in precision measurement equipment, medical devices, industrial control systems, and telecommunications infrastructure. Its high accuracy makes it ideal for analog-to-digital converters, voltage dividers, and sensor circuits. In aerospace and defense applications, these resistors are valued for their reliability under harsh conditions. They're also found in automotive electronics where stable performance across temperature ranges is essential.
Maintenance and Precautions
When handling TNPW08052K87BEEA resistors, avoid mechanical stress during assembly as it may affect performance. Ensure proper soldering techniques are used, with recommended peak temperatures not exceeding 260°C for 10 seconds. Storage should be in controlled environments (15-35°C, 20-70% RH) with protection from corrosive gases. Avoid exceeding the specified power rating as it may cause permanent resistance drift or failure.
B2B Procurement Guide
When procuring TNPW08052K87BEEA resistors in bulk, verify certification documents to ensure authenticity as counterfeit components are a concern in the electronics industry. Consider lead time variations (typically 8-12 weeks) when planning production schedules. For cost optimization, evaluate quantity breaks and consider alternative packaging options (tape and reel vs. bulk) based on assembly requirements. Establish relationships with authorized distributors to ensure consistent quality and technical support.
