LM383T FAQs

1.Q: Are there related parts to the PSFM5 with similar specifications?

A: Comparable parts might include LM386 (low-power audio amps) or TDA2003 (10W class-AB amps), but cross-check voltage/power requirements.

2.Q: What package does the PSFM5 amplifier use?

A: It uses a TO-220-5 (SFM) plastic/epoxy flange-mount package with through-hole terminals (non-surface-mount).

3.Q: What are the recommended operating conditions for the PSFM5?

A: Operate at 5V–20V Vsup, within 0°C–70°C ambient temperature, and ensure proper PCB layout for heat dissipation.

4.Q: What is the thermal resistance of the PSFM5 TO-220 package?

A: Not specified in the provided data, but TO-220 packages typically have a thermal resistance (θJA) of ~50–70°C/W without a heatsink. A heatsink is recommended for high-power dissipation.

5.Q: What are the absolute maximum ratings for the PSFM5 amplifier?

A: The supply voltage (Vsup) must not exceed 20V, and operating temperature should stay below 70°C. Exceeding these may damage the device.

6.Q: What are typical applications for the PSFM5 amplifier?

A: It’s suited for consumer audio systems, small speakers, intercoms, and other low-power audio amplification tasks requiring a single-channel output.

7.Q: What are the key features of the PSFM5 1-channel audio amplifier?

A: Key features include 11W output power, 30kHz bandwidth, 0.2% harmonic distortion, 5V–20V supply voltage range, and commercial-grade temperature operation (up to 70°C).

8.Q: What is the pinout configuration of the Rochester Electronics PSFM5 11W audio amplifier?

A: The PSFM5 has a 5-pin TO-220 package (JESD-30: R-PSFM-T5), with terminals in a single through-hole arrangement. Pin functions typically include power supply (Vsup), input, output, and ground, though the exact pinout should be verified in the datasheet.
