Description

The attenuator networks of IPEE contain a variable number of resistors connected as attenuators (symmetrical, asymmetrical, T, π and others), in a flat package with pins at a 2.54 mm pitch, for telecommunication equipment [1]. They are made for input impedances of 75, 135, 150 and 600 Ω and attenuations of 0.1…1.6 Np, with a maximum dissipated power of 0.5 W [1].

The Agenda radioelectronistului names IPEE Electro-Argeș of Curtea de Argeș as the producer of all the resistors in its section on resistors made in Romania, in both editions [3][4]. Un secol de electronică în România says that the works, founded in 1972 as ICEP, took over the resistor lines that IPRS Băneasa made under a Thomson-CSF licence: the carbon resistors in 1973 and the wire-wound resistors in 1974 [5].

The book gives the networks no series code [1]. Romanian resistors are generally marked in clear, with the series code, the nominal value (100 = 100 Ω, 1 K = 1 kΩ, 1 M = 1 MΩ), the tolerance [3].

The 1st edition (1983) gives the same data [2].

Dimensions in mm (fig. 16.7): length 10…16, height at most 10, pins 30 long at a 2.54 pitch [1].
