LC2512ATCZ

The LC2512ATCZ is a high‑precision, high‑power surface‑mount resistor designed for industrial current sensing, power supplies, and precision control circuits. It features a 2512 chip‑scale package, tight tolerance, low temperature coefficient, and environmentally compliant construction, making it suitable for harsh and high‑reliability applications.

The LC2512ATCZ is a metal glaze or thick‑film power resistor built on a high‑alumina ceramic substrate. The “LC” prefix denotes a precision power resistor series; “2512” refers to the 6.4 mm × 3.2 mm (25 × 12 mil) footprint; “A” indicates ±0.05% resistance tolerance; “T” specifies a temperature coefficient of ±50 ppm/°C; and “CZ” designates lead‑free, RoHS‑compliant packaging with tape‑and‑reel delivery. This device is optimized for stable performance under high current, high power, and wide temperature variations.

The resistor offers a rated power of 1 W, with some grades capable of 2 W under adequate heat sinking. Resistance values range from 0.01 Ω to 1 MΩ, with low ohmic values commonly used for current sensing. The tolerance is ±0.05%, ensuring accurate current and voltage monitoring. The temperature coefficient (TCR) is ±50 ppm/°C, maintaining stable resistance across −55 °C to +125 °C. The maximum working voltage is 200 V, and the component is rated for continuous operation in industrial environments.

Housed in a 2512 surface‑mount package, the LC2512ATCZ features a robust construction with a protective overcoat that resists moisture, dust, and chemical contaminants. The terminals are solder‑coated for good wettability and reliable PCB assembly. The resistor is designed for automated placement and reflow soldering. It operates reliably in temperatures from −55 °C to +125 °C and complies with RoHS and lead‑free requirements, supporting eco‑friendly manufacturing.

The metal glaze or thick‑film element provides low noise, excellent stability, and minimal drift over time. The device exhibits low inductance, which is critical for high‑frequency switching power supplies and fast current‑sense applications. It withstands high pulse loads and maintains performance under repetitive surge conditions. Strict factory testing includes resistance verification, TCR measurement, thermal cycling, and humidity exposure to ensure long‑term reliability in industrial and automotive systems.

Common uses include current sensing in DC‑DC converters, power inverters, and UPS systems; overcurrent protection and power limiting in motor drives and industrial controls; precision voltage division in instrumentation and measurement equipment; and high‑reliability circuits in automotive electronics and renewable energy systems. The combination of high power, tight tolerance, and low TCR makes it ideal for closed‑loop control and accurate power monitoring.

The LC2512ATCZ is supplied in tape‑and‑reel packaging suitable for high‑volume SMT assembly. It is fully lead‑free and RoHS compliant. The part number LC2512ATCZ specifies the 2512 package, ±0.05% tolerance, ±50 ppm/°C TCR, and lead‑free tape‑and‑reel format. It is widely available from distributors and component suppliers as a standard precision power resistor.
