Description
The β410 is a varicap diode of IPRS Băneasa, listed in the Agenda radioelectronistului (2nd edition, 1989) as withdrawn from production, in a DO-35 (F-80) glass package [1]. The package drawing is in the Gallery.
The code is printed „β 410”. The table gives no VRM, a junction temperature Tj of 150 °C, no capacitance at VR = 9 V, a capacitance Ctot of 7.5…11.5 pF at VR = 4 V, no capacitance ratio and a reverse current IRM of 5 µA at VR = 12 V [1].
A note to the table says that the β 310 and β 410 have been withdrawn from production („scos din fabricație”) [1].
The I.P.R.S. Băneasa Full Line Condensed Catalog (1990) lists the β410 among the „Variable capacitance diodes” of its „Small signal” section [2], with VR ≥ 12 V, Ctot 7.5–11.5 pF (f = 1 MHz, VR = 4 V), Ctot ratio 1.6 (4/9 V/V), DO-35 case [2].
The values given for the β410 elsewhere on this page [1] differ: package DO-35 (F-80), glass.
