Page 65 TDK Launches Series of EMC Filters
National City, CA — TDK Corporation has introduced the TDK-Lambda FQB series of EMC fil- ters, with a rating of 40 VDC at 20A. Voltage surge and spike protection for DC-DC converters is accom- plished through the use of active technology. The FQB has a rugged encapsulated quarter-brick package with a choice of flanged or non- flanged baseplates. These modules are suitable for use in a wide variety of harsh and demanding environ- ments, including MIL-COTS vehicle and airborne applications. The FQB series is designed with
a high differential and common mode noise attenuation, simplifying system level compliance to the MIL-STD-461 (F, G) standard. The modules also pro- vide input spike and surge protection per MIL-STD-1275(D, E) and RTCA/ DO-160G (Sec 16-18). Qualifying test- ing is consistent with MIL-STD-883F and MIL-STD-202G. The operating input voltage is
8.5 (start-up) to 40 VDC and the fil- ters can withstand transients of up to –50 to +210V. Reverse polarity
Stafford Intros Shaft Collars and Couplings
North Reading, MA — Clamp-type shaft collars, couplings and mounting devices that can be finished in custom colors to exactly match commercial OEM and military MIL product speci- fications have been introduced by Stafford Manufacturing Corp. Stafford shaft collars and cou-
plings with custom colors or finishes are offered in anodize aluminum, painted steel, chrome, and other platings. Available in a broad range of styles and sizes, they are ideally suited for matching commercial agri- cultural machinery and products and can include desert tan and olive green for military applications.

Customized shaft collars and coupling.
Providing a smooth bore to pro-
tect expensive shafts, tubing and pipes, the shaft collars and couplings are offered in sizes from 0.13 to 6 in. (3.2 to 152 mm) I.D. and various one- and two-piece styles. They can also incorporate threaded bores and a wide range of special face and O.D. treat-
ments, such as flats, holes and knurls. Contact: Stafford Manufacturing

and over-current protection is also provided. The filter modules have a remote on/off function and an open collector DC good/fault signal. No load input current is typically 3 mA but reduces to 1.5 mA when the remote on/off function is initiated. The PCB mount FQB can be
cooled using either an industry-stan- dard quarter-brick heat sink, or con- duction cooled with a cold plate. The non-flanged package size measures 2.4 x 1.5 x 0.5 in. (61 x 39 x 13 mm) and the flanged version 2.4 x 2.2 x 0.5 in. (61 x 56 x 13 mm). The total DC resistance of the filter is typical- ly 30 mW, minimizing power losses. The filters are available with
standard production screening (-S suffix) and a baseplate temperature rating of –40 to +239°F (–40 to +115°C), or with enhanced screening
(-M suffix) and an extended tempera- ture rating of –67 to +239°F (–55 to +115°C). Enhanced screening in - cludes functional testing at high and low temperatures and a 96-hour burn-in period with temperature cycling. All models have been safety cer-
tified to UL 60950-1, CAN/CSA C22.2 No. 60950-1-07 and IEC 60950-1, IEC/UL/CSA 62368-1 (pend ing) and
carry the CE mark. Contact: TDK-Lambda
