⚠️ Important Measurement Note: Please note that if hFE parameters are shown in photos, they were measured using a standard compact component tester (GM328/LCR class). Budget automated testers include the transistor's natural leakage current into the final hFE calculation, which often leads to higher/inflated gain readings on germanium transistors. Actual net gain parameters may vary depending on the specialized laboratory test equipment, applied collector current, and ambient temperature. Sold strictly according to the pictured tester readings.
