3Pcs Diy Lm317 Lm337 Negative Dual Power Adjustable Kit Supply Module Board Electronic Component

Description : FR-4 circuit plate board using military grade A material sheet, plate, and some stability tolerance parameters, A material behaved very tough, which is in the interests of a number of other relatively cheap price sheet. PCB board parameter elements are printed directly, without reference to a circuit diagram of the case can be soldered directly, very convenient. 1. The double-sided wiring, pads spray tin and tin increase Process pads, can withstand repeatedly desoldering, not easy to fall off. (Bending down refers to non-human conditions caused) 2. Since less likely to buckle, poor plate will change with time and the environment arising from bending. 3. Impedance more stable and reliable. Recommendation : input voltage (rectified smoothed voltage means rather than an AC voltage, AC input is rectified and filtered to 1.414 times, if the input voltage of 12V AC is rectified and filtered after 12 1.414 16.968V) at least higher than the output voltage is 3V, but do not be too Lees meer over de 3Pcs Diy Lm317 Lm337 Negative Dual Power Adjustable Kit Supply Module Board Electronic Component van huismerk in de productgroep elektronica
