1. SUBJECT
This specification applies on the metal film melf resistors
MEMF type (SMD style) was made by
SYNTON-TECH
Corporation。
2.
FEATURES
SMD style metal resistors.
Hi accuracy guaranteed ( tolerance ±0.1% & T.C.R.±15PPM/℃)
Free direction for mounting due to cylindrical design.
High solder ability due to specially plated electrodes.
Electrodes strength is higher than flat chip resistors.
Lower current noise than thick film flat chip resistors.
Suitable for reflow, flow and iron soldering.
