Notes  
(1) The pulse load stability of professional MELF resistors applies for precision resistors also. However, severe pulse loads are likely to jeopardize  
precision stability requirements.  
(2) Wave soldering is not recommended.  
(3) Special requirements apply to MICRO-MELF, MMU 0102:  
- R < 100  (0.15 % R + 10 m).  
- 100  
