| Metal GlazeTM Power Pack Surface Mount High Power Density Ceramic Package PPS-1 Series * * * * * * Low inductance 0.1 to 348K range Superior surge handling capability 150C maximum operating temperature 1 Watt performance - standard 2010 footprint Flameproof ceramic package provides superior temperature rise profile Electrical Data Size IRC Type PPS-1 Maximum Power Rating 1W Working Voltage 350 Maximum Voltage 700 Resistance Range (ohms) 0.1 to 0.99 1.0 to 348K Tolerance (%) 1, 2, 5 1, 2, 5 TCR (ppm/C) 100 50, 100 2010 Not to exceed ( P x R )1/2. Consult factory for tighter tolerances and TCRs. Applications The PPS-1 will dissipate 1 watt at 70C on a 2010 footprint. The PPS-1 is recommended for applications where board real estate or component/board TCE mismatch is a major concern. It is also recommended in circuits where a standard 2010 resistor exhibits marginal or unacceptable performance due to high power density/surge handling demands.
