The STK411-210E has a 12-pin SIP (Single In-line Package) configuration. The pinout is as follows:
+28V ———— 100nF ———— 4700µF ———— Pin 3 (Vcc) -28V ———— 100nF ———— 4700µF ———— Pin 6 (Vee) Signal IN ———— 2.2µF ———— Pin 1 (CH1 IN) Pin 4 (CH1 OUT) ———— Zobel ———— Speaker (+) Speaker (–) ———— Pin 5 (GND Power) Stk411-210e Datasheet
: Reuse a heatsink from a vintage amplifier rated for 50W/channel. Mount the STK module with thermal grease directly on the metal backside (no insulator needed). The STK411-210E has a 12-pin SIP (Single In-line
Uses IMST substrates for superior heat dissipation, reducing the risk of thermal runaway. reducing the risk of thermal runaway.
