BC MMB0207 0.1% resistors

[Andre Majorel]

Does anybody have experience with BC MMB0207 0.1% resistors ?
Rapid sell those for a fraction of the price of other 0.1%
resistors and I'm wondering what the catch might be.

Parameter BC MMB0207 Arcol MRA
------------------------------- --------------- ---------------
Resistance tolerance ą0.1% ą0.1%
Temperature coefficient ą15ppm 15ppm/°C
Voltage coefficent max. ? 5ppm/V

Power rating 0.4W 0.25W

Max working voltage 300V ?
Limiting element voltage ? 250V
Isolation voltage ? 500V

Temperature range -25°C to +125°C -55°C to +125°C
Climatic category 55/85/56 55/125/56

Dimensions (body) 6.3 x 2.5 5.6 x 2.3

Price 1+ (EUR) 0.235 0.711
Price 50+ (EUR) 0.198 0.653

The lower price reflects the vendor's prefered device - one that they
are prepared to distribute in small quantities with the minimum of
fuss.

The part cost is an order of magnitude less....

mmb0207 are surface mount, ie without radial leads.
