Often as low as 0.4% at rated power. Frequency Response: 20Hz to 50kHz. Input Impedance: Standard 55k Ωcap omega 4. Pinout Configuration
When working with the STK411-210E, always respect the absolute maximum ratings, use adequate heatsinking, and avoid 4Ω loads. With proper care, these modules can deliver warm, detailed sound that rivals many modern chip amplifiers.
The is a thick-film hybrid integrated circuit primarily used as a Class H audio power amplifier, though it also appears in industrial power control and specific TV applications. Performance Review
THD stands for Total Harmonic Distortion. A rating of <0.1% means that the amplifier adds very little distortion to the audio signal. This is considered and is excellent for a consumer audio amplifier of its era. Stk411-210e Datasheet
For more information on the STK411-210E datasheet, please refer to the following resources:
Operates on a dual (positive/negative) power supply.
Left and Right channel signals are sent to the input pins through coupling capacitors to block DC. Often as low as 0
Understanding its datasheet—paying close attention to its pin configuration, supply voltage limits, and thermal requirements—is essential for any successful repair or restoration project. When original parts are hard to find, the STK411 series offers several viable and often superior pin-compatible replacements, such as the STK411-240E. Always prioritize sourcing from reputable distributors to avoid counterfeit components, and ensure proper heatsinking to guarantee the longevity of this classic audio amplifier.
Silences the output stage when pulled to the designated reference voltage.
