The 0.050N lead space models are ideal for probes. Fig. 1: Wheatstone Bridge 2-Wire Interface HEL-775-A Ceramic SIP pkg. 0.100N lead spacing HEL-775-B Ceramic SIP pkg. 0.050N lead spacing -U -T HEL-775 platinum RTDs are designed to measure temperatures from −55° to +150°C (−67° to 302°F) in printed circuit boards, temperature probes, or other lower temperature applications. Solderable leads in 0.050N or 0.100N spacing provide strong connections for wires or printed circuits. 1000V, 0.00375 V/V/°C 100V, 0.00385 V/V/°C, DIN specification -0 ±0.2% Resistance Trim (Standard) -1 ±0.1% Resistance Trim (Optional) MOUNTING DIMENSIONS (for reference only) mm/in. HEL-775-A HEL-775-B Fig. 2: Linear Output Voltage CAUTION PRODUCT DAMAGE The inherent design of this component causes it to be sensitive to electrostatic discharge (ESD). To prevent ESD-induced damage and/or degradation, take normal ESD precautions when handling this product.
