Murata's Smallest signal line EMI suppresser
Murata just reduced the footprint of their smallest chip ferrite beads by 40% and the volume by 30%. The smallest in the Industry…again.
The new BLM02 family has nominal dimensions of 0.4x0.2x0.2mm, matching the size reductions of other passive components.

They provide EMI suppression and prevention of abnormal oscillation in cell phones power amplifier modules and those other space-limited designs that are increasingly popular. These beads function almost like resistors at noise frequencies. They greatly reduce the danger of resonance. They are especially useful when no stable ground-line is available because they need no ground connection. The design generates impedance from relatively low frequencies so they are effective in noise
suppression over a wide frequency range (typically 30MHz to several hundred MHz). Murata offers nominal values of 10, 70 and 120ohms, with rated currents of 500, 250 and 200mA respectively.

Panasonic Anti-Surge Chip Resistors as a Replacement of Melf Resistors
 Benefits:
Actually the market trend goes from Melf type Resistors to SMD Thick Film Resistors in order to
- reduce costs
- optimize mounting speed
- simplify mounting equipment (no nuzzle needed)
- better solder joint reliability against temperature cycles.
In order to meet the design engineers requirements, Panasonic succeeded in commercializing the compact Thick Film Chip Resistor with high power and high anti-surge characteristics suitable for industrial, measurement and telecommunication applications as well as for automotive circuits, like ECUs (electrical control unit) and air-bag systems.

Samtec has expanded its new high power-to-board interconnect system on (6,35mm) .250’ pitch (PES/PET Series) with signal pins on .100” (2,54mm) pitch (PESC/PETC Series). PowerStrip interconnects are rated for applications up to 28 amps at 80o C and have up to eight blade style contacts. Forty signal pins are standard and can handle up to 3 amps of current at 80°C.Powerstrips are available for parallel board spacings of 19mm, and for perpendicular and coplanar board interface applications. These polarized through-hole connectors can be used for rugged applications, and right-angle versions have screw-down features for added ruggedness. Samtec power connectors are RoHS complaint and suitable for lead-free processing.Samtec has a broad line of power and combination power/signal interfaces for board-to-board and wire-to-board applications
