Page 83 Cicoil: Flexible Flat Cables for Satellite Applications
Valencia, CA — Approved by NASA for spaceflight, Cicoil’s lightweight flat cables are designed to withstand extensive exposure to high levels of radiation, UV light and the dynamic temperature ranges of space –85 to +500°F (–65 to +260°C) with no adverse effects. Encapsulated with Cicoil’s pro-
prietary Flexx-Sil™ jacketing mate- rial, the crystal-clear flat cables offer uninterrupted performance, flexibili- ty and mechanical and electrical reli- ability, even after more than 50 years in space. This combination of features makes Cicoil a great choice for mission-critical space satellite applications. Each unique Cicoil flat cable can
incorporate a variety of separately encased elements, including power conductors, shielded signal pairs,
KOA Speer: High-Rel Metal Film Chip Resistors
Bradford, PA — KOA Speer Elec - tronics has developed the new high reliability RN73R series metal film chip resistors to meet the demanding requirements of high heat and high moisture applications. These new resistors provide
improved electrolytic corrosion resis - tance and high stability compared to
Ethernet, USB, HDMI, coax conduc- tors, and other design elements, such as Cicoil’s patented StripMount™ fas- tening strip, all in a single compact cable design. Cables are available in continuous lengths, space-sensitive custom shapes, cut to order, or as assemblies, complete with connec- tors of the customer’s choice. The tear-resistant outer
Flexx-Sil rubber jacket is self- healing from small punctures and will not wear, crack or deform during a lifetime of more than 10 million flexing cycles or long-term exposure to tight routing, vibra- tion, g-forces, operational stress and the harsh rigors of space. For applications that require abrasion and adhesion resistance, Cicoil
offers its spaceflight-approved
GlideRite™ anti-friction coating option by request. Cicoil’s contaminant-free, Class
1 Cleanroom-rated cables are manu- factured in an automated, climate- controlled environment, and exceed
the NASA 1124 and ASTM E595-93 outgassing specifications for space use and vacuum requirements of 1 per- cent total material loss (TML) and less than 0.1 percent collected volatile condensable material (CVCM). Cicoil’s flat cable assemblies
have been utilized on every Apollo, Mercury, Gemini, Skylab, Mercury Voyager and space shut- tle missions; and today are uti- lized on space transport rockets, probes, satellites and the interna-
tional space station. Contact: Cicoil, 24960

RN73R series metal film chip resistors.
KOA’s existing RN73 thin film resis- tors. The RN73R offers excellent heat tolerance with an operational temperature range of –67 to +311°F (–55 to +155°C) and a rated ambient temperature of +185°F (+85°C), as well as improved moisture tolerance of 85 percent for 1,000 hours at +185°F (+85°C). Power ratings and sizes for the
new RN73R are 0.063W (0402), 0.1W (0603), 0.125W (0805), and 0.25W (1206) with a resistance range of 10 to 1.5 MW, resistance tolerances ranging from ±0.05 to ±1 percent and TCRs of ±5, ±10, ±25, ±50 and ±100 ppm/°C. The new RN73R series metal film flat chip resistors are excellent
for applications that
demand high reliability, such as automotive electronics, industrial devices, medical devices, gain adjust- ment resistors for OP amp circuits, and dividers for power supply voltage monitors. The resistors meet EU-
RoHS requirements. Contact: KOA Speer Electronics,
