Pin 5 must be connected to Vout(-) at load. 2. Leave Pin 6 open for nominal output voltage. 3. Pin 7 must be connected to Vout(+) at load. 1) All dimensions in inches (mm) 2) Pins 1-3, 5-7 are 0.040” (1.02mm) dia. with 0.080” (2.03mm) dia. standoff shoulders. 3) Pins 4 and 8 are 0.062” (1.57 mm) dia. with 0.100” (2.54mm) dia. standoff shoulders. 4) All pins are Brass with Tin/Lead plating over Nickel 5) Tolerances: x.xx in. +/-0.02 in. (0.5mm) x.xxx in. +/-0.010 in. (0.25mm) 6) Weight: 1.20 oz. (34 g) 7) Workmanship: Meets or exceeds IPC-A-610B Class II OPTIONS The PQ48018QNA25 comes in two versions that differ by the sense of the logic used for the ON/OFF control signal. The PQ48018QNA25P version uses positive logic; mean- ing that the converter is on when the ON/OFF signal (Pin 2) is high. The PQ48018QNA25N version uses negative logic; the converter is on when the ON/OFF signal is low. Logic input is TTL compatible with an internal pull up. SAFETY The PQ48018QNA25 series of converters are UL 1950 recognized (US & Canada) with basic insulation rating and TUV certified to EN60950 requirements. The converters also meet 72/23/EEC and 93/68/EEC directives as well as 94V-0 flammability requirements for board and plastic components. An external input fuse must always be used to meet these safety requirements. 0.40 (10.2) 0.300 (7.62) 1.45 (36.8) 0.43 (10.8) 0.14 (3.6) 2.30 (58.4) 2.00 (50.8) 0.150 (3.81) 0.300 (7.62) 0.450 (11.43) 0.600 (15.24) 0.600 (15.24) 0.110 * (2.79) Top View Side View * Other pin lengths available ABSOLUTE MAXIMUM RATINGS Input Voltage: Non-Operating: 100V continuous Operating: 80V continuous 100V 10µs transients ,1% duty cycyle Input/Output Isolation Voltage: 2000V Storage Temperature: -55°C to +125°C Operating Temperature: -40°C to +115°C Voltage at ON/OFF input pin: +18V / -2V Patents: SynQor is protected under various patents, including but not limited to U.S. Patent # 5,999,417. |
