• Meander structured High Value Ch ip Resistors in Thickfilm
• Low temperatur e and voltage dependency
• High Working Voltage up to 3000 V
• Suitable for high vacuum applicatons – no organics
• High temperature application up to 300°C possible (CHM-HT)
• Non-magnetic (CHM only) Contact areas:
• CHM: PtAg for conductive glueing and soldering (non-magnetic, high temp. appl.)
• CRM: Nickel-barrier / matte tin Dimensions: L = Length, B = Width, D = Thickness, C = Width of wrap around (in mm) Packaging: Bulk in plastic bags – minimum quantity 30 pieces per value Blistertape acc. to IEC 60286-3 – minimum 500 pieces per value Reel diameter 180 mm or 330 mm Ordering Data: Type – value – tolerance – TCR – packaging Example: CHM 2512 10G ±10% TCR 100 Tape 180 mm Not trimmed parts are indicated by the extension “NA” in the order code: Type – value – tolerance – NA – TCR - packaging Example: CHM 2512 10G ±10% NA TCR 100 Tape 180 mm If no requirements for TCR and taping are given, the highest value in table will be supplied and packaging is bulk. Standard measuring voltage is 10V, other measuring voltages on request. Issue 07-2008 Size L B D C L B C D
