Notes
6S4P is the Latin transliteration of the Cyrillic designation 6С4П.
Quality suffix variants (6S4P-EV, 6S4P-DR) exist — only the base designation is catalogued here.
Compact dimensions: 23 x 40 mm, weight approximately 15 g.
Designed for high-frequency applications — low inter-electrode capacitances.
